Iron-doped ZnO was synthesized via hydrothermal method and investigated as a photocatalyst for CO2 photoreduction under both UV and visible light irradiation. The characterization of the samples was conducted through various techniques including X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), nitrogen adsorption-desorption, and UV-vis diffuse reflectance spectroscopy (UV-DRS). Results indicated that Fe-doping improved the photocatalytic activity under UV light, with 4% iron doping being the most efficient. On the other hand, 10% iron doping showed the highest efficiency under visible light. In conclusion, iron-doped ZnO shows promising potential as a photocatalyst for CO2 reduction under different light irradiations.
